If, after Cranwell and maybe a first tour, you end up heading to the JFH you will receive more training on 20(R) on the art of being a JEngO before being let loose on your own. As a grad you'll get 4 months shadowing the JEngOs, learning the Harrier specific policy, technical stuff, management and other vital tools of the JEngO trade. At each stage you have to sit and pass a knowledge board where you will be asked by SEngO 20(R) or other senior engineers questions on your knowledge. Finally the SEngO will recommend you as fit to take the Certificate of Competence board which is chaired by OC Eng/Fwd (Wg Cdr) and two Sqn Ldr/Lt Cdr engineers, one of whom is normally the SEngO of the Sqn you are due to go to. If you pass this grilling you get your reds and greens and are allowed to do the job for real.
Should sound familiar to RN AEOs. Caused a bit of a fuss when introduced to the RAF but it gives the JEngO a fighting chance when he gets onto the Sqn for real. It allows him to learn how it should be done and be introduced into how Lineys think(
) before he gets swamped with the additional Flt Cmdr stuff that he should already know from his first tour.
However, as people have already said you are always learning. Learning to take aircrew banter is all part of the fun!
However, if you want to stay in the CE side of things I imagine there are many different ways that the RAF will teach you things once you leave Cranwell.
